ICD-10 Code H61.113 – Acquired deformity of pinna, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H61.113 – Acquired deformity of pinna, bilateral
What it is
H61.113 identifies an acquired, noncongenital deformity affecting both external ears (the pinnae). Use it when documentation shows a bilateral shape or structural change of the auricle, not a birth defect.
Clinical signs
Findings may include visible distortion, thickening, scarring, or asymmetry of both pinnae. Clinical features vary; refer to documentation for the cause and extent of the deformity.
When to use this code
Use this code when the provider documents a bilateral acquired deformity of the pinna, such as after trauma, surgery, inflammation, or other noncongenital change. It fits charted ear deformity without a more specific diagnosis. If the record does not clearly state bilateral involvement, check documentation before assigning H61.113.
Do not use for
Do not use this code for congenital ear anomalies or for isolated external ear conditions that are not described as deformity. If the documentation only mentions pain, infection, or swelling without deformity, choose a different code.
Coding tip
Confirm that the record states both sides are affected and that the deformity is acquired, because laterality and origin drive this code choice.
